Take the vehicle to any auto parts store that offers to read the fault codes with a scanner for free and find out what that code is. If it shows Upstream or Downstream O2 sensor replace the O2 Sensor. There is a catch, dodge had an issue in the 2000 - 2004. The ECM will show a fault code that indicates the Catalytic converter is faulty. This is actually a faulty Downstream O2 Sensor. If you get a Catalytic converter fault code replace the O2 sensor first if you still have the problem then replace the converter.
